【 摘 要 】

The breakwater is the first barrier to prevent sea wave for entering the port basin and vital to provide a safe environment for ships or vessels. The stability of a breakwater in North China is studied by strength reduction method. This breakwater is constructed with silt-solidified fills in bags and armoured with accropode blocks and four-pin concrete hollow blocks. Calculation result shows that the factor of safety calculated by strength reduction method is 2.52, and the breakwater is in a good stable state since the ground and breakwater have no trend to slip.
